Functional Safety Testing for Safety Critical Systems

Functional Safety testing ensures that electrical, electronic and programmable systems operate safely even when faults occur. Whether used in industrial automation, transportation, energy, medical equipment or other high-risk environments, these systems must be designed and validated to avoid failures that could cause accidents, production stoppages or damage to people, assets and the environment. Kiwa supports companies throughout the entire Functional Safety lifecycle, from design and risk assessment to testing, according to the main international standards. Our experts work with your engineering and development teams to ensure compliance, reliability and readiness for market access.
